This plant was a rogue that grew in one of our veggie planter boxes, amongst the peas and lettuce. There were a bunch of them at first, but Spencer took out the other shoots as weeds. He left this one to grow, and now it's almost 3 feet tall, only has a couple of leaves on the way up, and then this is the top. We don't know what it is, and are waiting for its flower to open so we can see! (If you know what it is, don't spoil the surprise...) I think maybe it's a wee sunflower.
